As I suspected, Linux will get the HSA stack and compiler tools first. There is little incentive for MicroSoft to do much since Intel is not supporting HSA (as yet or if ever). But server apps will surely benefit hugely from HSA. As to the development of OpenCL 2.0, the pace depends on niche players like Altera, AMD and kronos group members. AMD has to champion the HSA runtime themselves for Kaveri. It seems like a couple of quarters away at best.Reply

I've been reading it for years. Normally it reads as a short news piece. Since AMD bought custom branding for a stream of its contents, I've felt that the pipeline items that appear from AMD Center have been below average quality; but this is a farce and a disgrace.Reply

Yes. Physics in iGpu via HSA stack and rendering on dGpu (via OpenCL or direct). Other fp-Ops can be on the iGpu has well with HSA depending on the compiler targets for CU resources. Potentially I see the HSA Runtime unit maybe tunable on each config so it can be manually optimized for some really heavy games like Crysis.Reply

Yeah but advantage is for only AMD since they have the only implementation with Kaveri. One can see that there are a couple of serious improvements needed to increase the Ram controller bandwidth of AMD's core compared to the Intel RAM bandwidth speeds. ALso, it is possible to mix GDDR5 RAM (like in PS4) with DDR3-2400 in a later iteration where the hUMA switch manages the ram segments for all the CUs to use. That would really super-charge the gpu cores.Looking even further, I can see AMD changing PCIe slot0 to a hUMA-Port so dGPU will be part of the APU as a full and equal CU. If you look back at AGP development, it is almost the same method. Sure if Nvidia wants to make hUMA-Port dGPU in future, they should be able to do so.This would be interesting when Arm 64bit server chips with HSA comes and has dual sided, hUMA-port connects. ie serious GPU compute clusters at low cost. I can hope since the HSA architecture has legs beyond they traditional design. It is a greater leap than many people thinks.Reply
